What are the main components of a battery?

There are many different kinds of cells. Different types of battery main ingredients are also different.As for dry cell, it has developed into a big family. So far, it already has more than 100 types,commonly including ordinary zinc-manganese dioxide dry cell, alkaline zinc-manganese dioxide dry cell, magnesium manganese dry batteries, zinc air battery, zinc oxide mercury batteries, zinc silver oxide batteries, lithium manganese battery, etc.

The main components of the common dry cell including mercury, carbon, lead, iron, zinc, manganese, cadmium, nickel and so on.

Lithium ion batteries(secondary battery, rechargeable) electrolyte was dominated by carbonate organic solvent, six of lithium fluoride phosphate and some additives.Batteries is mainly composed of positive plate, diaphragm, negative plate, electrolyte composition;Positive plate, diaphragm, negative plate coil or cascade, packing and infusion liquid electrolyte, after encapsulation make batteries.

Lead-acid battery electrolyte battery with sulfuric acid.

1. Battery components: the components of dry and rechargeable batteries, zinc (tin), carbon rod, mercury, compound, copper sulfate cap;The battery is given priority to with lead compounds.Example: 1, the composition of waste zinc-manganese batteries, weight 70 grams, which is 5.2 g, zinc 7.0 grams, 25 grams of manganese powder, copper cap 0.5 grams, other 32 grams.2. The types of batteries, battery are disposable battery, secondary battery and car battery.Disposable batteries include button batteries, ordinary zinc manganese battery and alkaline battery, disposable batteries containing mercury.Secondary battery mainly refers to the rechargeable batteries, which contain heavy metal cadmium.Auto battery scrap contains acid and heavy metal lead.3. The number of cells: DC, MP3 and other digital products in development, at the rate of super strong and used in the battery, the battery usage in a rapid increase, if don't take action, the phenomenon of battery mountain will happen sooner or later.

A,The lithium battery according to the shape points: well type lithium electricity (such as the commonly used cell phone batteries batteries) and cylinder (e.g., 18650);

Points, 2. Lithium battery outsourcing material: aluminum shell lithium-ion batteries, steel shell lithium-ion batteries,Soft package battery；

Three,. Lithium battery anode materials from (additive) : sell (LiCoO2) acid lithium batteries or lithium manganese acid (LiMn2O4),lithium iron phosphate batteries, disposable lithium manganese dioxide battery;Another point: lithium ion LIB, polymer PLB

Four, the performance of the different USES points:

One-time - lithium manganese batteries, button 3 v battery

High capacity (high platform), used in mobile digital products

High ratio;- used in electric cars and electric tools and model plane

High temperature;- a miner's lamp, room lighting, machine built-in back-up power;

Low temperature;-- - outdoor environment, () in winter in the north South Pole;

China electric car industry mainstream automotive batteries with lithium batteries are three iron lithium, lithium manganese, three yuan.

Lithium manganese 1. The price is cheap.2. Good low temperature performance, minus 20 degrees below zero discharge can have more than 90% efficiency.3. Good safety performance.

But he 1. The high temperature performance is poor (2) low cycle life (normal life in around 300-400) (3) g (112) 4. The specific capacity discharge difference (such as car uphill and quick start, a great influence on the battery)

Three yuan 1. The price is the most expensive 2. Three kinds of material high capacity (150.) can save the volume 3. Good cycle life (600 to 700) 4. The discharge

But he 1. Safety performance is the worst in three (especially steel shell) 2. The current Chinese battery industry mastery of the material is not yet mature, with not much.

Lithium iron (1) the price of 2. The capacity of (130) 3. The high cycle life (around 1500) 4. The high temperature performance is good 5. Discharge

But he 1. The price is not cheap (2) the low temperature performance is bad (3) on the electric car can fully demonstrate its superior performance (20 times can be 6 minutes on a full charge, discharge)

"Lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution.Lithium battery as early as 1912 by GilbertN. Lewis is put forward in this study.In the 1970 s, M.S.W hittingham and began to research on lithium ion battery are put forward.Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment.So, the lithium battery has not been applied for a long time.With the development of science and technology, the lithium battery has now become the mainstream.

Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries.Lithium ion battery does not contain lithium metal state, and can be recharged.The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries.Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.

Lithium battery:

Lithium batteries are generally use lithium manganese dioxide as positive pole material, metal or its alloy metal anode materials for batteries, the use of water electrolyte solution.

The basic principle of lithium battery

The basic principle of lithium battery

Discharge: Li + MnO2 = LiMnO2

Lithium ion battery:

Lithium ion batteries are generally use lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery.

For the charge on a positive response

LiCoO2 = = Li (1 -) x CoO2 + XLi++ Xe - (electronic)

For the charge on a negative reaction

6C+XLi++Xe-=LixC6

Rechargeable batteries overall reaction: LiCoO2 + 6 c = Li CoO2 + LixC6 (1 - x)

The anode

The anode materials: many optional battery anode materials, mainstream products with lithium iron phosphate.The positive materials of the different control:
